Recently, I also faced a similar issue with an error “ray.exception.WorkerCrashedError. The worker died unexpectedly while executing this task.”.

But the issue arose only when I use many cores. For example, if I generate jobs for 20 cores to calculate, ray gave me the error. However, if I reduce the core counts (but the same task) down to 10, the error disappears.

Currently, I am okay with 10 cores so this issue is not that urgent, but I am wondering this is a known issue or not.

Thank you in advance!
